LEAP® Bridge ConcreteIntegrated Analysis and Design of Concrete Bridges

LEAP Bridge Concrete is a powerful modeling and analysis solution for small to medium concrete bridges of all types: precast, cast-in-place, reinforced, and post-tensioned. This comprehensive bridge application offers a synthesis of geo-metric modeling, substructure and superstructure analysis and design, and load rating in a single, information-rich environment. Intelligent data management, computational modeling, and automated drawing production revolutionize the bridge delivery process.

Integrated Modeling and Documentation Workfl owsThe CONNECT Edition provides a common environment for comprehensive project delivery and connects users, projects, and your enterprise. With the CONNECT Edition, you now have a personal portal to access learning, communities, and project information. Your project teams can review project details and status, and gain visibility into project performance with the new project portal. Your project team may also wish to take advantage of the new ProjectWise® Connection Services including Project Performance Dashboards, Issues Resolution, and Scenario Services.

All-in-One Bridge Application Accelerates PerformanceInnovative analysis, design, and load-rating functionality come together in one advanced environment in LEAP Bridge Concrete. The direct exchange of project information – including bridge geometry, materials, loads, prestressing strand pattern, and shear reinforcement – helps users improve decision making for design and construction while connecting and enhancing workfl ow processes.

From a single interface, users tap into the full power of:• Computational bridge layout and design • Analysis, design, and load rating for post-tensioned (PT) and reinforced con-

crete box girder, T-beam, and slab bridges• Analysis, design, and load rating for simple- and multi-span precast and

prestressed concrete bridges• Analysis and design of reinforced concrete abutments, piers, and foundations

The resulting information provides a rich data asset for as-built documentation, maintenance, and operations. When combined with Bentley software for user col-laboration and project data management, LEAP Bridge Concrete becomes an ideal solution for professional bridge organizations, construction teams, maintenance and inspection crews, and bridge owner-operators. The software easily handles the vast majority of the bridges built today, making it the choice of bridge profes-sionals worldwide.

Design-to-Spec Ensures Code ComplianceLEAP Bridge Concrete automates design-to-specifi cation for U.S., Canada, or India bridge design codes to ensure compliance with mandated practices. The software is delivered for the user’s choice of international design codes:• American Association of State and Highway Transportation Offi cials

(AASHTO) specifi cations: » AASHTO Standard (LFD: Load Factor Design) » AASHTO LRFD (Load Resistance Factor Design) » AASHTO LFR (Load Factor Rating) » AASHTO LRFR (Load & Resistance Factor Rating)

• Canadian Highway Bridge Design Code (CHBDC) specifi cations• Indian Road Congress (IRC) bridge design specifi cations

The system has the fl exibility to mix and match design and rating methodologies for verifi cation. For example, users of the U.S. version can switch between LFD/LFR and LRFD/LRFR specifi cations.

Data Reuse Saves Time and Reduces ErrorsReuse of data helps users improve productivity as it eliminates the initial time wasted on data entry and reduces operator error – particularly as design modifi ca-tions are made and changes need to propagate throughout the entire bridge structure. Engineering professionals are able to focus on complex engineering issues and perform more analyses and code checks to refi ne their designs.

Use the integrated suite of LEAP modules via one GUI.

CONNECT Edition

Used by more than 1,800 bridge engineers worldwide, LEAP is developed by engineering professionals with expert knowledge of code specifi cations and design methodologies.

Users can defi ne detailed alignment, profi le, and cross-section information or directly obtain civil data from OpenRoads. Import of roadway information and ground data from LandXML fi les is also available.

ABC Wizard Speeds Bridge Defi nitionThe Automated Bridge Creator (ABC) wizard helps users quickly defi ne superstructure and substructure geometry and specify material properties. The software automatically generates full bridge models, enabling users to focus on analysis and design procedures. Users can defi ne the superstructure as prestressed girders, cast-in-place (CIP) reinforced and PT box girders, T-beams, or slabs. The substructure can be integral, drop-cap, tapered, inverted-T pier cap, or hammerhead type piers, with spread, pile, drilled shaft, or well foundation (India version) footings.

2D/3D Visualization Enhances Model Verifi cationPowerful visualization capabilities enable users to rapidly verify modeling input as they work. The bridge is viewed in profi le, elevation, and cross-section views. Solid and transparent viewing options aid in the exploration of areas with complex geometry. The software also produces 2D views of superstructure and substructure components, with dimensions, which can be saved in DGN or DXF formats for production of preliminary drawings.

The 3D Viewer lets users view superstruc-ture and substructure in 3D detail – down to

the reinforcement design. Longitudinal reinforcement, shear reinforcement, and PT-Tendons are shown for box girder bridges. Prestressing strands, deck longitudinal, and transverse reinforcement and stirrups are shown for precast girder bridges.

Flexural and shear reinforcement in cap, all reinforcement in columns, and fl exural and temperature/shrinkage reinforcement in footings are shown for substructure ele-ments. Users can specify the construction sequence and view a time-lapse construc-tion animation.

Unifi ed Database Ensures Project Consistency and AccuracyAll project information is recorded and stored in a LEAP database. This unifi ed database facilitates the software’s compu-tational design capabilities as well as the exchange of data with other bridge

enabled applications. Changes to the design trigger updates throughout the project, eliminating the need to make multiple, time-consuming corrections to all project components.

Integrated Design and Analysis Streamlines Workfl owLEAP Bridge Concrete provides a unifi ed environment for the design of superstructure and substructure. It delivers accurate and effi cient solutions for pier and abutment design, automating layout, analysis, and design of integral/monolithic piers as well as stem wall or pile cap abutments. Results from superstructure analysis are taken directly to the substructure model.

Use powerful visualization features to visually verify bridge models.

Bridge and LandXML Compliance Offers Direct Data Exchange

LEAP Bridge Concrete directly communicates with other Bentley solutions, including MicroStation®, OpenRoads, OpenBridge Modeler, and more. In addition, LEAP Bridge Concrete is LandXML registered and certifi ed, enabling users to directly exchange information such as horizontal alignments, vertical alignments, cross sections, and roadways with other applications that support LandXML.

Project Information Management Protects Data AssetsLEAP Bridge Concrete can be a data command center for your bridge projects. Reciprocal data exchange provides not only a seamless mechanism for information modeling, but also ensures the reuse and preservation of critical bridge information.

Drawing and Reporting Tools Automate Deliverables ProductionA drawing tab automates the generation of drawings based on the fi nal designs created. Drawings can be generated in MicroStation DGN format. User options are also provided for specifying border templates and symbol-ogy – commonly defi ned as *.dgnlib by most U.S. state departments of transportation.

Report generation options make easy work of publishing project information. Reports can be printed, saved as HTML fi les, or exported to spreadsheets.

AASHTOWare Integration Boosts Project StartupLEAP Bridge Concrete is integrated with the AASHTO BRIDGEWare database to ensure easy reuse of information and eliminate data entry that can take pre-cious time.

A Synthesis of Planning, Engineering, Design, and ConstructionWith the integrated process of LEAP Bridge Concrete, users synergistically develop a precise bridge data model that improves overall project accuracy and consistency. The results provide important information that proves to be a useful as-set, not just for the design phase but also for the life of the bridge. This synthesis of bridge information development can carry through all the project phases, from

conception to detailed design, design to fabrication and manufactur-ing, and construction to operations. Enable any person requiring information about a given bridge to access and reuse information relevant to his or her purpose during the lifecycle of the infrastruc-ture. For example, a structural detailer can access rebar information, a bridge modeler can extract key design measurements, and a road design engineer can access the exact geometry and position of the bridge deck from accurate as-built information.

Moreover, bridge owners can access historical trending, traffi c analysis, and cost information along with physical models of the infrastructure for capital project planning.

Bentley’s integrated products enabled LADOTD to respond quickly during challenging conditions to design a safer bridge with increased capacity and a longer life span, all while keeping the project ahead of schedule and $53 million under budget.
